The present invention has relation to eaves-trough-forming machines; andit consists in the novel arrangement hereinafter described, andparticularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawlngs.

In the accompanying drawings, 1 and 2 represent the end members of theframe,

which members may be substantially of the form shown in Fig. 5, whichend members are tied together by means of the longitudinal pipes 3.However, I do not desire to be confined to any particular manner oftying the end members, as the only object is in holding them in properspaced relation to each other, and any mechanical means may be employedto accomplish this object.

The center member 4 of the frame is substantially of the form shown andis also held in place by the longitudinal pipes 3, which pipes arepassed through suitable apertures formed in the end members and thecenter member.

The power-shaft 5 is properly j ournaled at its ends in suitablebearings located upon one of the end members and the center member ofthe frame, which power-shaft is provided with the tight and loosepulleys 6 and 7, said pulleys being of the ordinary construction. Uponthe power-shaft 5 is mounted the pinion 8, which pinion meshes with thegearwheel 9, which gear-wheel is loosely mounted upon the cam-shaft 10and is thrown into and out of action with reference to the cam-shafttive, parts are in the position shown in Fig.

1 l but when it is desired to bring the clutch into operative action thelever 14 is moved downward, which rocks the clutch-shaft 13 and movesthe clutch-arm 11 by means of the link 15, and thereby permitting thespring-actuated clutch-pin 16 to engage. the

aperture 17, which aperture is formed in the hub of the gear-wheel 12,thereby causing said gear-wheel to rotate the cam-shaft 10. Theclutch-pin 16 is provided with the lug 18, which lug is so situated thatas the clutchpin comes into engagement with the beveled head 19 it willmove the clutch-pin endwise and disengage it from its aperture and freethe wheel 9, so that said wheel is free to rdtate looselyupon theclutch-shaft 10. For the purpose of automatically bringing theclutch-arm 11 back into its normal position the spring 20 is employed,which spring automatically lifts the lever 14 after it has beendepressed.

For the purpose of holding the clutch-arm 11 in proper position theguide-arms 21 and 22 are provided, which arms ride upon the hub of thewheel 9.

For the purpose. of limiting the movement of the lever 14 theclutch-shaft 10 is provided with the fixed arm 23, which arm is extendedupward between the stop-pins 24, which stop-pins limit the movement ofthe clutch mechanism.

For the purpose of giving the cam-shaft the proper friction to stop the.machine proper when the clutch is released the camshaft is providedwith the collar 25, upon which collar is mounted the split flangedcollar 26, which is frictionally held by means of the bolt 27 and ofcourse the amount of friction being regulated by the adjustment of thenut 28. In the end and center members of the machine proper is journaled the rockshaft .29, which rock-shaft extends the entire lengthof the machine, or substantially so, and upon which rock-shaft aresecurely attached the cam-actuated levers 30, which cam-actuated leversare extended above and below the rock-shaft 29, as best illustrated inFig. 6. The bottom or lower ends of the levers 30 are provided withsuitable pins 31, which pins should be provided withantifriction-rollers and arranged so as to fit the camgrooves 32, saidcam-grooves being of such a shape that they will properly time themovements of the levers 30 for the purpose hereinafter described. To thetop or upper ends of the levers 30 is adjustably attached thepresser-bar 33 by means of the lug-bolts 34, which lug-bolts arepassedthrough the slots 35.

Upon the rear edge of the presser-bar 33 are attached the plates 36,which plates carry the setting-bolts 37, which setting-bolts arescrew-threaded and are moved longitudinally back and forth until theyare brought into such a position that their inner ends will come incontact with the upper rear face of the levers 30, after which theresser-bar is securely and firmly connected by means of the lug-bolts34.

To the end members 1 and 2 is properly journaled the trough-formingvmandrel 38, which mandrel is formed of such a size that an eaves-troughof a predetermined size will be properly formed.

It is well understood that in the formation of eaves-trough they are tobe provided upon one of their longitudinal edges with a suitable bead,and in order that an eaves-trough and its bead can be formed at oneoperation the beading-rod 39 is provided. I

At the operating end of the cam-shaft 10 is mounted the gear-wheel 40,which communicates rotary motion to the gear-wheel 41, which gear-Wheel41 is securely attached to the mandrel 38. The gear-wheel corresponds insize with the gear-wheel 12, secured to the opposite end of thecam-shaft 10, said gear-wheel 12 being forthe purpose of communicatingrotary motion to the gearwheel 42, which gear-wheel is securely fixed tothe opposite end of the mandrel 38, thereby roviding a means for drivingthe mandre 38 at both ends.

The purpose of driving the mandrel at both ends is to prevent anytwisting of the mandrel, and owing to the fact that the gearing is thesame at each end of the machine so far as the mandrel and the cam-shaftis concerned both the mandrel and the cam-shaft will bedriven with equalforce at each of their ends. To the mandrel 38 is securely attached thelate or bar 43, which plate or bar is seate 'in the groove 44 andsecurely held by means of suitable screws or lug-bolts 45 or theirequivalents. The plate or bar 43 is provided with a semicircular groove46. Upon the top or upper side of the plate or bar 43 is located thebar47. in proper relationship with reference to each other by means ofsuitable screws or their equivalents 48. The bar 47 is provided with thegroove 49*, which groove, together with Said bars 43 and 47 are held thegroove 44, produces, when the bars are placed in the positionillustrated in Fig.6, an open recess or chamber, in which recess orchamber is located the beading-rod 39, said beading-rod being formed ofadiameter somewhat less than the diameter of a partial circle inclosedby the walls of the grooves formed in the bars 43 and 47, so that thebeading-rod 39 is free to turn axially and at the same time provide roomto receive between the walls of the grooves in the bars and theperiphery of the beading-rod the thickness of the metal from which thebead of the eaves-trough is made.

It will be understood that in order to form a bead the beading-rod musthave an axially movement or rotation, and in order to produce thisaxially movement or rotation the toothed segments 49 are provided, whichtoothed segments 49 are fixed to the end members 1 and 2 of the frameand are held in fixed relationship therewith by any suitable means.

The beading-rod 39 is provided with the angled end 50, which angled endis for the purpose of engagement with the angled socket 51, formed inthe end of the beadingrod-actuating shaft 52. Upon theheadingrod-actuating shaft 52 is securely mounted the pinion 53, whichpinion meshes with one of the toothed segments 49*, and when rotarymotion is imparted to the mandrel 38 by means of the gear-wheels abovedescribed a planetary movement will be imparted to the beading-rod 3,9,which planetary movement carries the pinion 53 over and in engagementwith one of the toothed segments 49 thereby imparting an axiallymovement to the beading-rod simultaneously with its planetary movementaround the mandrel 38. The toothed segment 49 and the pinion 53' beingso formed or geared that a single planetary movement of the beading-rodaround the mandrel will impart but one complete axially rotation of thebeading-rod, by which arrangement the beading-rod is always brought intothe proper position to expose the groove 49 which groove is for thepurpose of receiving one of the longitudinal edges of the sheet fromwhich the eavestrough is to be formed.

In the formation of eaves trough the sheets must be cut into strips ofsufficient width to produce a proper-formed eavestrough, and in orderthat the strips can be slid into position for engagement with thebeading-rod the gear-wheel 41 is provided with the slit 55, which slitallows the sheet of metal to be moved endwise between the adjacent facesof the slit formed in the toothed ring or periphery of the gear-wheel41. The sheet metal when placed in position to be acted upon is in theposition illustrated in dotted lines, Fig. 6, and after a sheet has beenplaced in the position illustrated the lever 14 is moved down, whichdownward movement brings the clutch into engagement with the cam-shaft10, and the entire machine is brought into action, the initiatorymovement of the mandrel does not impart axially movement to thebeading-rod owing to the fact that the pinion 53 is out of engagementwith its toothed segment 49*, and the pinion held against rotarymovement by means of the sliding detent 56, which sliding detent engageswith the groove 57, which groove is continued through the entire widthof the pinion 53, including the integral and non-toothed portion 58. Thedetent 56 is provided with the head 59, which head is so located that asthe mandrel continues to rotate it will pass into the groove 60, formedin the inner face of one of the toothed segments 49*.

At the entrance of the groove 60 there is provided a cam-shaped wall 61,which cam-' shaped wall is so formed that it will move the detentoutward and disengage it from the groove 57, at which time the pinion isfree to rotate when brought into engagement with its toothed segment 49,and when a complete revolution of the pinion 53 has been made it willhave passed beyond its toothed segment 49 and the groove 57 brought intosuch a position that the detent will register with said groove andbeforced into the groove by means of the spring 62, and thereby lock thepinion against rotation and stop it at a point when the beading-rod 39has been brought into the position illustrated in Fig. 6, which is theposition required for inserting a sheet of metal from which aneaves-trough is to be made.

The beading-rod-actuating shaft is journaled in the housing 63, whichhousing is pivctally attached to the flanges 64 by means of the pin orbolt 65, which pin or bolt forms a hinged connection for the housing 63.The pin or bolt is provided with the grooved head 66, which grooved headforms a guide for the movement of the detent 56. The flanges 64 areformed integral with the head 67, which head is secured to the mandrel38 in any convenient and well-known manner.

It is well understood that after an eavestrough has been properly formedit is necessary to remove it from the mandrel and its beading-rod, andin order that this may be done the housingv 63, together with all thedifierent partscarried thereby, is moved or turned upon its bolt or pin65 into the position illustrated in Fig. 4, and when in that position itis out of the way and the finished eaves-trough can be removed and a newsheet placed in position to form an eavestrough, as above described.After the sheet has been brought into position the housing 63 is placedin the position illustrated in Fig. 3 and the beading-rod-actuatingshaft moved longitudinally by means of the ribbed or toothed bar 68,which toothed bar meshes with the annular grooves and ridges 69, formedupon the shaft 52. The toothed bar 68 is provided with the toe 70, whichtoe is free to pass through the slot 71 when in the position illustratedin Fig. 4, and after the toe has fully passed through the slot theribbed or toothed bar 68 is rotated by means of the handle 72, therotation of which looks the housing and moves the bead-actuating shaft52 endwise and connects said shaft to the beading-rod by means of itsangled socket 51 and the angled extensions 50, and when said parts areso connected the machine proper is in position and condition to form aneaves-trough.

It will be understood that during the time an eaves-trough is beingformed the sheet should be held in close contact with the man drel 38,and in order to so hold the'sheet of metal the presser-bar 33 isprovided and is attached to the cam-actuated levers 30, and for thepurpose of reducing the friction a series of antifriction-rollers 73 areprovided and are located upon the forward edge of the IIO , presser-bar38 and held in proper position by l the combination of a frame, aneaves-troughmeans of the straps 7 4, which straps constitute journalsfor the rollers. The camgrooves 32 are so formed that the presser-barwill be thrown into the position illustrated in Fig. 6 at the time asheet is to be introduced,

but by the action of the cams after the heading-rod and its plates havebeen carried out of the way of the presser-bar said presser-bar is movedtoward the mandrel and the antifriction-rollers carried by thepresser-bar brought into proper contact with the sheet of metal.

For the purpose of preventing the beading-rod 39 from twisting thepinion 53 is connected to the opposite end of the rod from that to whichthe pinion 53 is detachably connected, and of course a toothed segment49 is to be employed, said toothed segments being located at oppositeends of the machine.
